    • PURPOSE: A battery pack is provided to lower the height of a connected solder part when at least two unit cells connect to a protection circuit module in series or parallel, and to widen the contact area of a conductive lead of a connecting circuit substrate and the solder part, thereby improving the reliability of connection. CONSTITUTION: A battery pack(100) comprises a plurality of unit cells(111), a connecting circuit board(120) connected to the unit cell, a conductive lead(121) discharged from the connecting circuit board; a protection circuit board(130) in which an opening is formed to be inserted of the conductive lead; and a solder part formed by solder-bonding by being inserted of the conductive lead. The conduction lead comprises an insert part inserted into an opening(133), a bending part formed to be bended from the inset part, and a separation hole formed to be separated of the inset part.
    • 目的:当至少两个单元电池串联或并联连接到保护电路模块时,提供电池组以降低连接的焊接部件的高度,并加宽连接电路基板的导电引线的接触面积和 焊接部分,从而提高连接的可靠性。 构成:电池组(100)包括多个单元电池(111),连接到单电池的连接电路板(120),从连接电路板排出的导电引线(121) 保护电路板(130),其中形成有导电引线插入的开口; 以及通过插入导电引线焊接而形成的焊料部。 导电引线包括插入到开口(133)中的插入部分,形成为从插入部分弯曲的弯曲部分和形成为分离插入部分的分离孔。
